4.
Phylum Porifera
• Also known as SPONGES
• Have PORES or HOLES in their bodies and a
single large opening called osculum
• Filter feeders
• Has two layers of cells
-epidermal cells
-collar cells

5.
Phylum Cnidaria
• Hollow, tube-like bodies
• Presence of nematocyst
• Bodies are composed of two layers of tissue:
epidermis and gastrodermis
• Food is ingested and expelled through the
gastrovascular cavity

6.
Sea Anemone

7.
Hydra

8.
Phylum Platyhelminthes
• Commonly known as flatworms
• Flat bodies
• They posses only a hollow sac with a single
opening for food and waste excretion

9.
Liverfluke

10.
Marine Worm

11.
Phylum Nematoda
• Commonly known as roundworms
• Round bodies covered with cuticle
• Ascaris and hookworms are examples

12.
Phylum Annelida
• Characterized by ring like body parts
• Have similar segments throughout their
bodies
• Presence of mouth and anus
• Have hearts and blood vessels

13.
Phylum Mollusca
• Have soft bodies but they have hard
protective shells as outer body covering
• Mussels, clams, and oysters are examples

14.
Phylum Arthropoda
• Most diverse of all the phyla
• Exhibits cephalization
• Well developed nervous system (brain and nerve
cord)
• Have segmented bodies
• Body is divided into 3 segments (head, thorax
and abdomen)
• Exoskeleton is made up of chitin
• They molt or shed their exoskeleton as they
grow up

15.
Phylum Echinodermata
• Has a tube feet system of canals
• For sucking in seawater to obtain nutrients
and for expelling wastes.

16.
Phylum Chordata
• Three distinguishing structures:
-notochord
-skull
-vertebral column or backbone

17.
Major classes of Vertebrates
•
•
•
•
•
•
•
Agnatha (jawless fishes)
Chondrichthyes (cartilaginous fishes)
Osteichthyes (bony fishes)
Amphibia
Reptilia
Aves
Mammalia

18.
Class Agnatha
• Jawless fishes but have sucking mouth parts
• No paired fins, jaws or scales
• Notochord serves as the skeleton of
agnathans

19.
Class Chondricthyes
• Skeletons are made up of cartilage
• Have gills, fins and scales
• Have toothlike scales

20.
Class Osteichthyes
•
•
•
•
Called bony fishes
Skeletons are made up of bones
Scales are flattened
Presence of swim bladder

21.
Class Amphibia
• They generally live in or near bodies of water
• Early stages on water, adult stage on land

22.
Class Reptilia
• Have hard body coverings (scales or plates)
• Sharp claws on their toes adapted for climbing
and tearing prey
• Cold-blooded organisms
• They breathe through their lungs
• Most are egg laying

23.
Class Aves
•
•
•
•
•
Feathers cover the bodies of birds
Presence of beak or bill for food getting
A pair of wings that enables them to fly
Warm-blooded animals
All of them are egg-laying

24.
Class Mammalia
•
•
•
•
Presence of mammary glands
These secretes milk (in females)
Warm blooded animals
They reproduce through sexual means
